How much does basement waterproofing cost?

• <div><p>The <a href="https://www.angi.com/articles/how-much-does-basement-waterproofing-cost.htm">cost of basement waterproofing</a> is <b>$4,950</b> for the average homeowner. However, you could end up paying between <b>$600 and $14,000</b>, depending on factors like basement size, waterproofing method, and the region you live in. </p><p>If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between <b>$2,500</b> <b>and $5,000</b> to waterproof, but that price rises significantly for a larger basement. </p></div>

What are the disadvantages of trench drains?

• <div><p>Trench drains have a bit of a reputation as being difficult to clean, so if there’s a massive rainstorm that leads to a lot of debris and gunk getting stuck in the drain, you’ll spend extra time cleaning it out. Plus, you definitely need to regularly clean the drain, heavy rainstorms or not, to keep it in good condition, adding an extra step to your cleaning to-do list.</p></div>

Q: What other projects should I do at the same time as installing a sewer backflow preventer?

• <div><p>If you&rsquo;ll be digging up your floor to get access to your pipes when putting in a sewer backflow preventer, this would also be a good time to take care of any other plumbing issues or renovations. For example, you could install additional pipes for a basement bathroom. Since the floor will be sealed over with concrete when you&rsquo;re done, now&rsquo;s a good time to take care of those bigger tasks.</p></div>

Q: Should water in the basement go away on its own?

• <div><p>Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It&rsquo;s important to <a href="https://www.angi.com/articles/how-fast-can-water-damage-ruin-home.htm">deal with water damage</a> as soon as it occurs.</p></div>

Q: How long does flooded basement cleanup take?

• <div><p>Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.</p></div>

Marlo was a real find. We had a serious leak on one of our single family family rental residences dating back to November. Initially, we had a so-called leak specialist for a $350 minimum fee who totally mis-diagnosed the location of the leak and blamed it on on a "debris dam" in one of the...
